These shocks are horrible.
Martin (Illinois) | January 28th, 2018
These shocks are horrible. I had one go bad 6 months after I got them. Had to buy a replacement cause the stock ones are to short. So going on 2 years later. Both rear shocks are blown and another front is blown. Thankfully I have the third front shock I can replace them with. But I had to put stock ones in the rear. Biggest problem is fox themselves. It's going to cost 90 dollars per shock to fix plus parts, plus shipping and ill have to do it again in two years. Going to be cheaper to buy brand new shocks. Plus the ride quality sucked. I have a 4-6 inch lift and it rides so stiff my dash broke in 3 spots. And I only have the lift at 3 inches so I'm not even running the lift. Other thing is I drive on the street I don't off road my truck.
